The steps are as follows:
1. Drain the old water: Find the drain valve on the cooling system and drain the old cooling water. Be sure to use appropriate containers to collect waste water and dispose of it properly.
2. Add new water: Open the cooling system water inlet valve and slowly pour in new cooling water until the cooling system is completely filled. Make sure you use the correct amount of cooling water.
1. Do not add water during operation
You should know that it is not recommended to add water during operation of the diesel generator after starting the engine, because there in a. No cooling water in the body, different parts of the engine will quickly rise in temperature, especially the water jacket outside the cylinder head and the injector of the diesel engineL. If cooling water is added at this time, the cylinder head and water jacket will collapse easily. crack or warp due to sudden cooling. 2. Precautions when adding water during shutdown (1) Heating water in winter. During the cold winter, it is difficult to start the generator. If cold water is added before starting, it is easy to freeze in the lower chamber of the water tank and in the water inlet pipe during the water filling process or when the water is added but fails to start. be started in time, preventing water from circulating, it may even cause the water tank to burst. Adding hot water can, on the one hand, increase the engine temperature (2) Add clean, soft water. After filling the water tank with antifreeze, if you find that the liquid level in the water tank has dropped, simply add fresh, clean water (waterdistilled is better) assuming no leaks, because the boiling point of commonly used ethylene glycol antifreeze is high, what evaporates is the water contained in the antifreeze, it is not necessary to replenish the antifreeze but only fresh water. It’s worth mentioning: never add unsoftened hard water. (3) Fresh water selection. Fresh water generally includes rain water, snow water, river water, etc. This water contains few minerals and is suitable for engine use. The added water must be clean. Impurities in the water will block the water channels and worsen the wear of the water pump impeller and other components. If hard water is used, it must be softened first. Softening methods typically include heating and adding lye (usually caustic soda).
